Ha Tang for AI coding agents

Claude Code, Cursor, Copilot and other coding agents can now read these docs as Markdown and work with Ha Tang directly: an MCP server, ready-made rules for your project, and five task-shaped recipes.

• MCP server @hatang/mcp 0.1.0. npx -y @hatang/mcp gives an agent search_docs and read_doc (no key needed) and, with an API key, tools to send email, check domains, create and simulate VietQR payments, read e-invoices, work the inbox and add knowledge for the AI assistant. --read-only keeps it to lookups. See MCP server.
• Docs for machines. /docs/llms.txt lists every page, /docs/llms-full.txt holds the whole hub, every page has a Markdown copy at its URL plus .md, and the OpenAPI spec is at /docs/openapi.json. The same in Vietnamese under /vi/docs.
• Rules for your project. One AGENTS.md section, a Cursor rule and a Claude Code skill that tell an agent which SDK to use, where the key lives and how to verify payments and webhooks. See Use Ha Tang with AI coding agents.
• Recipes. Email from Node.js, VietQR payments, Zalo ZNS from code, live chat on a website and e-invoices through the API.
